Stop program from M-Code

Hello,

I'm trying to setup a simple Mcode which asks to the user if some actions were performed before continuing with the program. If the actions were performed the user clicks on Continue, whereas if the actions were not performed the user clicks on STOP and the program stops. Here is the simple Mcode.

The problems is that when I send the halcmd command I get an error: "can't do that emc_task_plan_run in auto mode with interpreter reading" and the program doesn't stop. Do you how to stop the program with halcmd?

Thank you

Francesco

You could try halui.abort, though the docs say that they both do the same thing.

Hello,

I already tried halui.abort but I get the same error.

Francesco

Do you get the same result if you connect a GUI (or physical) button to the stop / abort pins?

If you do then I think that means something is wrong.
Which version of LinuxCNC?

I just checked what Axis does
github.com/LinuxCNC/linuxcnc/blob/master...cripts/axis.py#L2287
And there seems to be no mode-switching there.

A workaround might be to switch your M-code to Python, though that definitely should not be necessary.

I will try to remember to check the behaviour in different versions and scenarios tonight. I feel that this might be a bug.

Hello,

thank you for your reply. I will check tonight to connect a GUI button to see if it works. The version I use is the 2.7.13

Francesco

It works for me

exit 0

OK,

so tonight I will try your modified script.

Thank you

Nothing, for me it does not work

I always have the same error, @andypugh using a normal GUI button works...very strange

I did some experiments.

I can get that error message by making the M101 file not executable.

The error message is unhelpful and wrong.

My M-code was always executable. The permissions are: -rwxr-xr-x

Which version of linuxcnc did you use?
